Uses and working notes

Common uses: musical instrument parts, piano keys, pool cues, carving, small specialty items.

Durability: Very durable, holding off both termites and various insects.

Workability: Extreme density makes machining hard; its oiliness complicates gluing, but it buffs to a brilliant sheen.
